Toilet fill valve filling from tiny hole near the top?

[GJ_DAN]

I installed a new toilet fill valve a few months back, it came with a plastic tube to connect to the tiny hole and I figured that's how it must fill. Looking at my other toilet after it had a problem, no water comes from the hole at the top at all and there's no plastic tube there. So I feel maybe this one is faulty somehow, even though it seem to do the job?? I'll attach a pic of the tube it's coming from. Fingers pointing at it. Thanks in advance.

What brand of inlet valve?

Its ok mate it doesn’t fill from there , you may get a small amount of water coming down it as the valve operates , no problem its just its design

They fill from the bottom of the stem of the valve, mainly to keep the noise of filling down as the outlet is underwater all of the time.
